Information
This information is part of the Modelica Standard Library maintained by the Modelica Association.
Extends the model CellStack by a series of RC-elements, describing the transient behaviour of the battery.
This model can be used for a single cell Ns = Np = 1 as well as a stack built from identical cells.
For details, see concept and parameterization.
Note
Parameter record array rcData contained in parameter record cellData has to be specified.
The total inner resistance is the sum of the resistance of resistor r0 and the sum of the resistances of the resistors of the RC-elements.
